ERNST LINDNER, OF NEYV YORK, N. Y.

G A S B U R N E R SPECIFICATION forming part of Letters Patent No. 5 5, 7, dated December 14, 1397- Application filed December 3, 1896. Serial No. 614,808. (No model.)

To all whom it may concern.-

Be it known that I, ERNST LINDNER,a citizen of the United States, and a resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

This invention relates to gas -burners of that type wherein provision -is made for the retention of a small flame when illumination is not desired. 1

An object of the invention is to provide novel and efficient means for raising and lowering the hood, which is adapted to slide on the burner to shield the small flame and protect it against extinguishment. When the hood is elevated, the plug of the cock is at the same time so adjusted as to reduce the flame to very small proportions, and when the hood is lowered the plug of the cock is simultaneously so adjusted as to increase the flame to its full capacity.

A further object of the invention is to improve the means whereby the supply of gas to the burner is regulated so as to maintain at will a large flame or a small flame.

The invention is shown in the accompanying drawings, in which- Figure 1 is a front elevation of a burner embodying my improvements and showing the hood in its lowermost position. Fig. 2 is a central vertical section showing the hood in its elevated position, the means for raising it being shown at the rear. Fig. 3 is a section on the line 3 3 of Fig. 1, looking to the left; and Fig. 4 is a section on the line 1 4. of Fig. 3.

In all the views like parts are indicated by like numerals of reference.

In the drawings, 5 indicates the casing of the cock; 6, the plug, which is tapered as shown and is so shaped at its enlarged end. as to conform to the contour of the valve-casing and thus furnish a smooth neat finish. At its top the casing is provided with extension 7, adapted to receive a gas-burner 8 of usual construction, and at its bottom with an internally-screw-threaded extension 7, whereby the device may be secured to a gas-pipe.

The hood 9, provided with the usual mica windows, is adapted to slide on the burner 8. In Fig. 1 the hood is lowered to expose the large flame and in Fig. 2 is elevated to protect the small flame.

The means whereby the hood 9 is raised or lowered comprises a segment-gear, one part of which, 10, is pivoted to the extension 7 of the casing and is provided with an arm 10, having a rounding or curved top surface, while the other part, 11, is secured to the small end of the plug of the cock and is provided with a pair of arms 11 11 The arm 10 of the gear 10 is beneath the hood 9, the latter adapt ed to rest on said arm and the arm being adapted to lift the hood which slides on the arm when the cock is adjusted to provide a small flame only. This arm is shown passing through a loop 12, formed on the bottom of the hood, thus connecting the arm to the hood. This is a desirable construction, but is not essential, as the arm will lift the hood when not connected to the latter, and when the arm is lowered the hood will fall from its own weight.

To the ends of the arms 11 11 of the segment-gear 11 there are connected the chains 13, by which the hood elevating and lowering mechanism may be operated and the plug simultaneously adjusted.

The plug 6 is hollow longitudinally for a portion of its length, as at 14, and this opening is in communication with opening 15, made in the wall of the plug and which is adapted to register with the inlet-opening in the easing of the cock when the plug is adjusted to obtain a full flame, as may be seen in Figs. 3 and 4. The plug 6 is also provided with three small openings in its surface diametrically opposite the large opening 15. These small openings are indicated at 16 10 16 and they are in communication with the longitudinal bore 14. The central small opening 16 is in the path of a channel 17, which extends from the edges of the large opening 15 clean around the plug. I

In the extension 7 of the casing of the cock there are drilled three channels, as shown in Fig. 3, and which are indicated by 18 18 18 These channels are adapted to register with the openings 16 16 16 when the plug is adj usted for a full flame, the gas passing to the burner through all of said channels in the casing, as seen in Fig.

'When the plug 6 is adjusted, as shown in Fig. 2, its opening 15 is opposite the solid wall of the chamber of the casing and its small openings 16 16 16 are out of register with the corresponding channels in the extension 7 of the casing of the cock, and a small supply of gas only is permitted to pass by the plug along the channel 17, which remains in register with the central channel 18 in said extension 7 of the casing. Gas, when the plug is thus adjusted, will fill the longitudinal bore 14, passing from the channel 17 through opening 16 in the path of said channel, and thus a supply is provided sufficient to maintain combustion at the moment the plug is shifted to its other position.

The screw 19, passing through the side of the casing of the cock and entering the channel 18 is adapted to be adjusted to regulate the size of the small flame, as will be understood from Fig. 2.

It will be understood, of course, that the adjustment of the plug to its two positions is accomplished by pulling on the chains 13. The depression of the left-hand arm ll of the segment-gear 11 turns on the full flame and at the same time lowers the hood 9, while the depression of the right-hand arm l1 reduces the flame and elevates the hood.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the casing of a gas-cock and its plug, ofv a segment-gear connected to the end of said plug and adapted to move with the plug and provided with a pair of operating-arms, and a second segment-gear pivoted to the casing of the cock to intermesh with the first-mentioned segment-gear and provided with an arm adapted to lift a hood which slides on said arm.

2. In a gas-cock provided with aburner, the combination with a hood adapted to slide on the burner, of a segment-gear pivoted to the casing of the cock and provided wit-h an arm upon which said hood is adapted to rest and by which the hood is elevated by sliding on said arm, and a second segmentgear connected'to the end of the plug of the cock and meshing with said first-mentioned gear and provided with a pair of operating-arms.

3. In agas-cock provided with a burner, the combination with a hood adapted to slide on the burner and provided with a loop, as 12, of a segment-gear pivoted to the casing of the cock and provided with an arm passing through said loop on the hood, and a second segment-gear connected to the end of the plug of the cock and meshing with said first-mentioned gear and provided with Operatingarms at. As a new article of manufacture, a gascock consisting of a casing and a plug, a segment-gear secured to one end of the plug to turn therewith and provided with a pair of operating-arms, and a companion segmentgear pivoted to the casing to intermesh with the first-mentioned seginentgear and provided with an arm having a rounding or curved top surface.

Signed at New York, in the county and State of New York, this 1st day of December, 1896.

ERNST LINDNER.
